Description
Technical Field
The present invention relates to oil field production equipment; in particular to a connecting protection device specially used for a hydraulic feedback oil well pump in an oil field.
Background
At present, when the conventional tubular oil well pump and hydraulic feedback oil well pump used for sucker rod pump oil extraction in oil field are used in oil well with relatively bad well conditions such as deep hanging, sand-containing, slurry-out, well deviation, scaling and corrosive gas drive, etc., the problems of low pump efficiency, short pump detection period, low lifting efficiency, etc. exist. In addition, when the hydraulic feedback oil well pump enters the underground well, the pump body is not protected under the condition of severe well conditions, so that the pump body is damaged. Therefore, it is a new problem to be solved urgently to develop a connection protection device specially used for a hydraulic feedback oil well pump.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a connection protection device specially used for a hydraulic feedback type oil well pump, which has the protection function on the hydraulic feedback type oil well pump when entering the underground after being connected with an upper pump cylinder and a lower pump cylinder, so that a pump body cannot be damaged. In particular, the hydraulic feedback oil well pump is effectively protected during the production of complex oil wells such as deep pumping, large well deviation, sand production, carbon dioxide gas drive and the like.
The purpose of the utility model is realized as follows: the utility model provides a be exclusively used in connection protection device on hydraulic feedback formula oil-well pump, includes pump barrel bearing joint, coupling, outer casing, pump barrel bearing joint's upper end and last pump barrel threaded connection, pump barrel bearing joint's lower extreme external screw thread and the one end internal thread connection of coupling, pump barrel bearing joint internal thread and the external screw thread connection of pump barrel down, the other end internal thread of coupling and the external screw thread connection of the one end of outer casing, the other end and the ferrule threaded connection of outer casing, ferrule and tail pipe threaded connection.
The main point of the utility model is its structure. The working principle and the using operation method are as follows: the working principle is that when the hydraulic feedback oil-well pump enters the well, a connecting protection device specially used for the hydraulic feedback oil-well pump is connected with the pump body, so that the pump body is protected when going into the well. When the pumping unit is used, the upper pump barrel A is connected with the upper well pipe through the pipe hoop, and the tail pipe D is inserted into the lower part of the oil well.
Compared with the prior art, the protection device has the following advantages: (1) the structure is simple, the cost is low, and the manufacture is easy; (2) the pump body is protected, and the pump barrel is not damaged; (3) particularly, the hydraulic feedback oil well pump is effectively protected during the production of complex oil wells such as deep pumping, large well deviation, sand production, carbon dioxide gas drive and the like; (4) the device is deeply popular with the users.
The present invention will be described in detail below with reference to the accompanying drawings and examples.

Fig. 1 is a schematic structural view of the present invention.
Detailed Description
Referring to figure 1: the utility model provides a be exclusively used in connection protection device on hydraulic feedback formula oil-well pump, includes pump barrel bearing joint 1, coupling 2, outer pillar 3, pump barrel bearing joint 1's upper end and last pump barrel A threaded connection, pump barrel bearing joint 1's lower extreme external screw thread and coupling 2's one end internal thread, pump barrel bearing joint 1 internal thread and lower pump barrel B's external screw thread threaded connection, coupling 2's the other end internal thread and the external screw thread connection of the one end of outer pillar 3, outer pillar 3's the other end and ferrule C threaded connection, ferrule C and tail pipe D threaded connection.
The working principle and the using and operating method of the connection protection device are as follows: the working principle is that when the hydraulic feedback oil well pump enters the underground, a connection protection device specially used for the hydraulic feedback oil well pump is connected with an upper pump barrel A and a lower pump barrel B of a pump body, and meanwhile, the upper end of an outer protecting pipe 3 is connected with a pump barrel bearing joint 1 through a coupling 2, and the lower end of the outer protecting pipe 3 is connected with a tail pipe D; thereby protecting the pump body when the pump body is lowered into the well. When the pumping unit is used, the upper pump barrel A is connected with the upper well pipe through the upper pipe hoop, and the tail pipe D is inserted into the bottom of the oil well.
